Do you use 0.8.2 or latest indev build?

If you don't use indev, could you try it and reproduce same manipulations to see if it works or if it's still generating an error.

0.8.2

[ThibautSF]

You answer faster than I edit the message ^^

I'm asking that because I've got someone on the forum which reports a similar bug.
I added more error catching (in order to write it in DebugLog file) and looks like I also change a line which solved the problem.

[AdrianSimionov]

Do you have nightly builds somewhere? More than happy to try a Dev build, I am on OSX Catalina.

[AdrianSimionov]

OK, So it does work, once I manually create all 3 JSON files and added 1 mod by hand.

I think the fix would be to create all 3 JSON files if they do not exist and populate it:
dlc_load.json
game_data.json
mods_registry.json

The whole idea of using this Mods Manager was for the corner case when the game is not launched via Steam.

[ThibautSF]

I will note that.

The only needed file by PMM is dlc_load.json

A normal use is to execute the launcher and activate one mod with it (no need to start the game) and it should create all needed files.

[ThibautSF]

For dev builds, there is an indev tag in releases which contain the latest build each time I push the tag (which I usually push each commit which add a functionality I consider functional).

You can also look the readme.md and build from source.
(you should just need to download and install a JDK 11 and set java home)

The problem is the Launcher does not work for Stellaris on OSX. Only the game.
